How A Whole House Water Filter System Work

The basic principle of this product is the same in different models.

Let’s find out.

People usually attach filters to the main water line before the water heater so it can filter all water into the house.

In the filtration system, water meets a sediment pre-filter to remove large particles like mud, sand, rust, debris or sediment. This filter also helps other filters work for a long time without changing often.

The journey of water continues to pass through the activated carbon filter to eliminate a lot of contaminants. You can imagine activated carbon with a large porous surface, many nooks and crannies to absorb pollutants.

Now, you have water that removes most of the chlorine, residual sediments, volatile organic compounds, odors, and water flavors.

Some manufacturers also add silver in carbon filters to help antibacterial.

Next, water flows through the copper and zinc filters to remove the remaining contaminants such as remains of chlorine, heavy metals, bacteria, and other common microorganisms and also reduces the scale in the water.

By this stage, manufacturers give you some options for additional filters.

Some filters transmit water through a water softener or descaler or use ion exchange technology to do this. Ion exchange filters include plastic particles filled with sodium ions.

When magnesium and calcium particles meet ions filled with ions, they replace sodium ions. Then, the water will soften and taste slightly salty. You can use salt-free water softeners to keep the neutral taste.

Or some filters produce high-quality water by preventing tiny particles in the water. These filters are like a mesh filled with holes up to 0.35 microns.

Another one is the UV filter to kill remaining bacteria, viruses or microorganisms. So, it is an excellent choice for high bacterial contamination.

Whole House Water Filter Systems Buying Guides

The Filter Lifespan

Most whole home water filter systems need low maintenance. You only need to change the water filter periodically depending on the product.

But it’s inconvenient when you’re not good at doing it and need a plumber and have to turn off the water for some times.

The tip here is to choose a filter lasting for at least six months. And note that there are good filters for years depending on water quality and frequency of use.

Consumption

Why calculate the water consumption of your whole family? To buy a product with a suitable filter, you need to know how much water your family uses in a day, week, or month.

At that time, you don’t have to change filters too often when it’s cheap and operates at high frequency. Or if your home uses less water with a filter lasting more than five years, it will cause clogging.

The Flow Rate Of The System

You need to buy a product with a large flow rate when your family has a lot of members to serve the water needs quickly.

The whole house water filter systems often have water flow rates from 15 GPM to 20 GPM (Gallons Per Minute) to indicate the amount of water filtration through the system. And high GPM helps you to keep water pressure stable.

Micron Size

You should know one micron is one-thousandth of a millimeter.

To choose the correct filter size, you need to check the water in your home. If you do not have a high pollution water source, the filter blocking particles larger than 1 micron is suitable.

In contrast to highly polluted water, you should use the best filter to prevent anything larger than 0.35 microns at a higher price.

NSF/ANSI Standards

NSF proves the standard of drinking water filter for each type of treatment. You can see the NSF mark on a product like NSF / ANSI 53 or NSF / ANSI 42 indicating the standard of the filter.

You can visit the NSF website to check the details of these standards. This certification helps to you know that the filter has proven quality through the robust tests of the most prestigious organizations in the US. Therefore, you can use it safer.

Due to the high cost of certification, smaller businesses may not be able to afford it, so their products can have the WQA seal (Water Quality Association) or be tested in the independent trusted laboratory.
